Privacy Policy

Your privacy is important for us. We are transparent, comply with privacy regulations such as GDPR, and provide this privacy policy in an understandable language free of legalese.

Who collects the data?

The legal entity which owns Splitways apps is:
I-Mars Limited
191 Java Road, North Point Hong Kong

What data do we collect and why?

  • Full name - to identify users who have access to your group
  • Email address - to identify users who have access to your group, to identify your account, to back up your data, to generate an email with data export from the app, for marketing campaigns (which you can opt out of)
  • Profile picture(s) - to visually enhance the app and to easily distinguish the users and members of a group
  • Your Splitways data - transactions, members, groups, history of changes for the basic functionality and backup
  • Receipt images - when you attach a receipt to an expense, for records and group collaboration; if you enable optional AI auto-fill, the selected image may also be processed to suggest expense fields (see below)
  • Analytics data - anonymized logs of your behaviour, clicks on elements, time spent on screens etc. to make data-driven decisions about the development of the app and detecting UX issues
  • Crash reporting data - details about the crash with diagnostic information about your device, network, language etc. to fix crashes

Where are the data stored?

All our data are stored in Google Cloud Platform. We specifically use services called Firebase and Google AppEngine. The servers are located in the United States and Taiwan.

How are the data secured?

Google Cloud Platform is trusted by many businesses worldwide and they have one of the best security in the industry. On top of that, we provide our data only via HTTPS (an encrypted connection). This way, your data cannot be intercepted on the way, for example when connected to an unsecured WiFi network. We take security very seriously and take every measure to prevent data leaks. If you suspect any security issue, contact us immediately at imars@i-mars.cc.

What is shared with other users of Splitways?

Other users who are in the same group(s) as you can access your:

  • Name
  • Email
  • Profile picture(s)
  • Transaction & other data you enter into the app
  • Receipt images you attach to shared expenses

These are visible on the Permissions page of your group(s).

What is shared with third-parties?

We don't share your data with any third parties except:

  • Google - provider of our backend services (database, file storage, analytics, crash reporting, web hosting, Google Play app statistics). When you use optional AI receipt auto-fill, the receipt image you select is also processed by Google Cloud AI services (including Vertex AI / Gemini) solely to extract suggested expense fields;
  • Apple - iTunes Connect app statistics;
  • Microsoft - Windows Store app statistics;
  • when required by law or necessary to comply with a valid legal process;
  • in relation to a sale of all or part of our business.

We do not sell your receipt images or personal data to advertisers.

Optional AI receipt scan and auto-fill

Splitways offers an optional Premium feature that can read a receipt photo and suggest expense details (such as amount, currency, date, and description). It is available only to Premium members or members of an active Premium group, and only when you keep the in-app “AI fill” option turned on.

  • When enabled, the image you select may be sent to our cloud servers and processed with Google Cloud (Vertex AI / Gemini) to return structured suggestions for you to review and edit before saving.
  • AI parse results are returned for form fill-in; we do not separately store AI-generated JSON as standalone files.
  • If you save an expense with receipts, those images may still be stored under our normal receipt-upload flow (for example Firebase Storage) for expense records—separate from the AI parsing step.
  • To prevent abuse, we may keep short-term usage counts (rate limits) related to your account.
  • You can turn AI fill off at any time, skip camera/photo access, or enter expenses manually. Auto-filled values are suggestions only—please verify them before saving.

If you do not agree to sending a receipt image to cloud AI for processing, please leave AI fill disabled.

How long are the data stored?

Indefinitely, unless the service is shut down—except that images used only for real-time AI parsing are not retained by us as separate long-term AI-only files. Receipt images you choose to upload and save follow the same retention as your other Splitways expense data until you delete the related expense or account (or as required by law).

How to export all your data?

Both iOS and Android app have built-in PDF export for users' expense history. If you need extra information, contact us at imars@i-mars.cc.

How to delete my account & data?

If you wish to permanently delete your Splitways account and all associated data, please visit our account deletion page. This will remove your account, all sub-accounts, expense records, receipt images, and personal data from our systems.

Warning: This action is permanent and cannot be undone.

How to raise a complaint?

Contact us at imars@i-mars.cc.

What happens when the service is shut down?

We will try hard to avoid that, but we offer no guarantees for data losses. In the case of an expected service shutdown, we will contact all users by email at least one month prior to the shutdown so you can export all your data.
